Step #1: Understanding Washing Machine Drain Code Requirements
What Is the Standard Washing Machine Drain Size?
According to the Universal Plumbing Code, the standard drain size for a washing machine is 2 inches. This size is crucial because it allows for the efficient removal of water, preventing backups and flooding in your laundry area.
- Why 2 Inches? Larger loads and more powerful machines need that extra capacity to handle the water flow.
- Minimum Requirement: While 2 inches is standard, the minimum requirement is 1.5 inches. However, going larger is often better, especially if you're dealing with high-efficiency machines.
Common Washing Machine Drain Code Errors
1. Incorrect Pipe Size: Using a pipe that is too small can lead to clogs and slow draining. Ensure your drain pipe is at least 2 inches in diameter.
2. Improper Slope: The pipe should have a slope of 1/4 inch per foot to ensure proper drainage.
3. Incorrect Venting: Venting prevents vacuum lock and allows water to flow smoothly. Ensure your setup includes adequate venting.
Real-World Example: Consider Jane, who used a 1.5-inch pipe for her high-efficiency washer. Within weeks, she faced frequent clogs. After upgrading to a 2-inch pipe, her drainage issues vanished.
How High Should Standpipes Be From the Floor?
Standpipes should be installed between 18 and 30 inches from the floor. This height prevents the trap from drying out and keeps water flowing smoothly.
- Why This Height? It ensures gravity helps the water flow effectively into the sewer line.
- Avoiding Mistakes: Installing a standpipe too high can cause backflow issues.
Step #2: How to Plumb Your Washing Machine Drain
How to Attach the Trap and Standpipe
Materials Needed:
- 2-inch PVC pipe
- PVC cement and primer
- Pipe cutter
- Level
Installation Steps:
- Check Local Codes: Ensure your plans are compliant with local plumbing codes.
- Cut the Pipe: Use a pipe cutter to cut your PVC pipe to the desired length.
- Prime and Cement: Apply primer to the outside of the pipe and inside of the fittings.
- Attach Fittings: Cement the fittings to the pipe, ensuring a tight seal.
- Use a Level: Ensure the pipe is level to prevent drainage issues.
- Vent the System: Install a vent pipe to prevent vacuum lock.
Should Standpipes Be Vented?
Venting your standpipe is crucial. It prevents the build-up of pressure and ensures smooth drainage.
- Air Admittance Valve (AAV): An AAV can be a practical solution if traditional venting isn’t possible.
- Local Codes: Always check if AAVs are permitted in your area.

Pro Tips for Successful Plumbing:
- Use Quality Materials: Invest in durable PVC pipes and fittings to ensure longevity.
